The 897-6 Chicago Pneumatic 1” Heavy-Duty Air Impact Wrench has all the same great features as the 897, plus a 6-inch extended anvil for tire work. It is perfect for high volume truck tire shops. The high performance motor provides maximum power (1300 ft-lbs of torque and a free speed of 3800 rpm) while minimizing air consumption. It is the lightest 1-inch impact wrench in its class at only 16.25 lbs. This wrench features a teasing throttle to make bolt starting easy, and has a convenient reverse valve.
